All-round inerting safety protection device for closed coal bunker

Abstract

The invention relates to an omni-directional inerting safety protection device of a sealed coal bunker, belongs to the technical field of safety protection of sealed coal bunkers and aims to solve the problem that the inerting effect of the inside of sealed coal bunkers in the prior art is not ideal. The provided omni-directional inerting safety protection device of the sealed coal bunker comprises a coal bunker body, a lift, pressure relief anti-explosion doors, a material inlet, a temperature sensor, a combustible gas sensor, a smoke sensor, guide ways, a movable gas exchange loop, a fixed gas inflation loop, an inert gas storing tank, valves, a pressure reliever, a clean water storing tank, a pressurization device, a coal bunker outlet gas locking device, a fine water mist dust removal cooling device, gas inflation steel cables and laser distance measuring sensors. According to the omni-directional inerting safety protection device of the sealed coal bunker, the inflation mode of various inert gases is adopted, the fixed gas inflation loop on the wall surface and the gas inflation steel cables are included, and therefore, the problem of non-uniform inerting of the inside of the coal bunker can be effectively solved.

Description

technical field [0001] The invention relates to an all-round inerting safety protection device for a closed coal bunker, which belongs to the technical field of safety protection for a closed coal bunker. Background technique [0002] With the rapid development of my country's social economy, the demand for coal is also increasing. However, the open-air stacking of coal not only causes huge pollution to the surrounding environment, but also accelerates the oxidation of coal due to weathering and rain in the open-air stacking, which reduces the quality of coal and causes economic losses to enterprises. The use of closed coal bunkers for coal storage not only solves the problem of environmental protection, but also has the advantage of occupying a small area, and can adapt to various climatic conditions, reducing the loss of coal, and also in line with the country's increasingly stringent environmental protection policies. . However, as a relatively closed container, the clo...
